Another early-detection method being developed works by smelling huanglongbing infections in trees. This method detects the different scents plants give off. Researchers at the University of California, Davis have created a test that could lead to advances in fighting huanglongbing (HLB) disease in citrus. Researcher and professor of mechanical and aerospace engineering, Christina Davis, said the test looks for a …
A bit of weight was lifted off of Florida citrus growers’ shoulders after hearing the U.S. Department of Agriculture’s initial 2016–17 Florida citrus crop forecast that calls for 70 million boxes of oranges. Citrus industry members gathered at Florida Citrus Mutual’s Political Action Committee Clay Shoot and Crop Estimate Luncheon to hear the live forecast from Southeast AgNet. The event, …
Every year, the Citrus Expo seminar program provides a wealth of new research information for growers.

By Bob Rouse and Mongi Zekri Little can be done to protect trees and fruit from hurricane velocity wind, but we can take steps to protect the people, equipment and supplies that will be needed for the recovery. Below is a checklist for citrus grove managers. Pre-Hurricane Preparation Checklist Personnel assignments: 1. Make a list of all tasks and make …
By Gülcan Önel and Derek Farnsworth The U.S. agricultural sector has a long history of dependence on foreign workers, and the Florida citrus industry is no exception. Even though mechanical harvesting systems saw increased usage between 1999 and 2006, the discovery of citrus greening in 2005 and its subsequent spread across Florida virtually eliminated mechanical harvesting efforts by 2015 in …
Jim Graham, soil microbiologist for the University of Florida’s Institute of Food and Agricultural Sciences, was recognized at the 73rd annual Florida Fruit and Vegetable Association (FFVA) convention for his years of service to the industry. Graham was named FFVA Researcher of the Year at the association’s award luncheon. His recent research has led to some major discoveries on the …
By: Ernie Neff Mexican fruit flies were a major nuisance to Dale Murden this spring. “As a fresh fruit grower in south Texas, I have to say Mexican fruit fly is our biggest worry,” the citrus grower and president of Texas Citrus Mutual said. The fruit flies infested Texas’ three-county (Cameron, Hidalgo and Willacy) citrus industry in November 2015, prompting …
By Carlene Thissen, Mike Bayer and Fritz Roka The U.S. Department of Labor classifies anyone who for a fee “solicits, recruits, furnishes, hires, employs, houses, and/or transports” seasonal and migrant farm workers as a farm labor contractor (FLC). This article provides an overview of the rules and responsibilities that agricultural employers must keep in mind when driving workers to their …
By Tripti Vashisth and Troy Gainey In the last 11 years, Florida orange production has declined more than 60 percent. This dramatic reduction in yield is attributable to multiple causes, including loss of citrus acreage in the state, citrus canker and other diseases, but huanglongbing (HLB) is now recognized as the primary reason for declining citrus yields. HLB-affected trees are …
By Stephanie Slinski Evaluating how well bactericides, nutritional programs or other treatments work against HLB can be difficult. Symptoms are not uniform between trees in a grove, and tree health fluctuates throughout the season, which may give the appearance of an effect. Rigorous field trials are the best way to test new treatments, but not every treatment program can be …
By Megan Dewdney, Jeff Rollins, Nan-Yi Wang and Ke Zhang Citrus black spot (CBS) has become established in the groves of Collier and Hendry counties. In other citrus-growing regions of the world where CBS is present, the sexual fruiting bodies of the fungus, known as pseudothecia, form in decomposing leaf litter. Approximately 50 to 180 days following leaf drop, the …
By: Brad Buck GAINESVILLE, Fla. — A chemical treatment known as a bactericide could help preserve citrus trees from the potentially deadly and costly greening disease, a new University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) study shows. Citrus is estimated as a $10.9 billion-a-year industry in Florida and the finding could be key to helping the state’s …
By Marcos Fava Neves The first crop estimate was released in May for the 2016–17 citrus season in Brazil, which should be of great interest to Florida’s citrus industry. ACREAGE AND AGE The area of orange groves in Brazil, including all varieties, is 416,843 hectares (ha) —6.2 percent smaller than the 2015 figure. There was a considerable reduction of 27,882 …
By Stephanie Slinski and Harold Browning (Editor’s note: Click on the graphs throughout the article to enlarge them.) Bactericides have been available to growers as a new tool to improve the health of HLB-infected trees since early March 2016. This use has been under a crisis declaration from the Florida commissioner of agriculture, but on August 15 of this year, …
Asian citrus psyllids are detected sporadically in the San Joaquin Valley — home to most California oranges and mandarins — and are endemic in Southern California lemon country. But as far as anyone knows, the pests that spread HLB in Florida and Texas have not spread the disease into California’s commercial citrus groves. California HLB detections have been limited to 17 …

The Citrus Research and Development Foundation (CRDF) has selected AgNet Media, owner of Citrus Expo and Citrus Industry magazine, to administer a grower survey on bactericide use. CRDF is asking that all Florida citrus growers participate in the survey so that the industry can gain a better understanding of how these products are being used against HLB. Three commercial bactericide …
By: Pete Spyke President of Arapaho Citrus Management, Inc. Bill Castle’s recent Letter to the Editor (see January 2016 Citrus Industry) called for our industry to engage in dialogue about HLB that is different from our usual kinds of communication.
